Problem to connect a Fedora PC

[lukeb]

I’m trying to establish a connection between a Fedora 23 PC and and Ubuntu 15.10 PC inside a LAN.

I’ve installed NoMachine for Linux 5.0.53 on both PCs. From the Fedora PC I’m able to make a connection to Ubuntu without a fuss.

When I try to do the same from Ubuntu to Fedora I can establish the connection but I got this error:
“The server was unable to make the local display available or access to the local display is disabled.”

What could be the problem?

NoMachine doesn’t currently support the Wayland X server (though we are working on adding it) and Fedora 23 uses this X server as default. You can temporarily switch to lightdm which will use Xorg instead.

Steps to change display manager from gdm to lightdm are as follows:

Install lightdm:
[root@test01 ~]# dnf install lightdm

Disable GDM:
[root@test01 ~]# systemctl disable gdm

Enable LightDM:
[root@test01 ~]# systemctl enable lightdm

Reboot to make changes effective:
[root@test01 ~]# reboot

/b.
